Having a graphic design background, I did note the quality of the collage. Probably all cut and pasted by hand. Released in 1990, it was just slightly before good, relatively affordable photo editing software. And unless it's just the image, there appears to be some really conspicuous airbrushing on the brothers as well.

Anybody else notice a similarity to the poster for Smokey and the Bandit? I can't decide if its a coincidence, unconscious imitation or an intentional ripoff.
